ANTISKIDDING DEVICE.

Application filed March 29, 1916.

To all whom it may concern:

Be it known that I, TOM A. Fi nos, a citizen of the United States, res1d1ng at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Ant 1- skidding Devices, of which the following is a specification.

This invention .relates to an anti-skidding device for tires, andhas for 1ts ob ect to provide a device of such type, in a manner as hereinafter set forth, including antiskidding members formed of vegetable fiber and extending transversely of the tread of the tire whereby during the travel of the wheel said members will reduce skidding or slewing of the wheel to a minimum.

Further objects of the invention are to provide an anti-skidding device for pneumatic tires which is simple in its construction and arrangement, strong, durable, efiicient and convenient in its use, readily set up with respect to the tire, and inexpensive.

With the foregoing and other objects in view the invention consists of the novel construction, combination and arrangement of parts as hereinafter more specifically described and illustrated in the accompanying drawings, wherein is shown an embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the claim hereunto appended.

In the drawings wherein like reference characters denote corresponding parts throughout the several views, Figure l is a side elevation of a wheel, broken away, showing the adaptation therewith of an anti-skidding device in accordance with this invention. Fig. 2 is alike view of a modified form of anti-skidding device. Fig. 3 is a similar view of still another modified form of anti-skidding device. Fig. 4 is a detail, broken away, illustrating the antiskidding member employed in the form shown in Fig. 2. Fig. 5 is a detail, broken away, illustrating an anti-skidding member of the form illustrated in Fig. 3. Fig. 6 is an elevation of a blank from which a modified form of coupling member is set up. Fig. 7 is a side elevation of a modified form of coupling member set up from the blank shown in Fig. 6. Fig. 8 is an elevation'of a blank from which the coupling member shown in Fig. 4 is set up. Fig. 9 is a side elevation of the same bent into its finished Specification of Letters Patent.

form with the retaining member of the device indicated by dotted lines.

Referring to Figs. 1, 2 and 3 of the drawings 1 denotes a tire, 2 the rim, and 3 the spokes of a wheel.

An anti-skidding device in accordance with this'invention consists of a pair of annular retaining members constructed of rope and the said members are adapted to be positioned, one at each side of the outer shoe of a pneumatic tire. To said retaining members are attached coupling members which are secured to anti-skidding members arranged to extend transversely with respect to the tread of the tire. The antiskidding members are spaced from each other. But one of the retaining members is illustrated and which is indicated at 4 in Figs. 1, 2 and 3.

Referring to Figs. 1 and 2 the coupling members are indicated at 5 and each of which consists of a split sleeve 6, having serrated edges 7. Projecting from the outer end of the sleeve 6, is an arm 8 having a hook-shaped free end 9 which is slitted as at 10 and the material freed by the slit 10 pressed inward to form a securing barb which engages in the retaining member 4.

Referring to Fig. 1 of the drawings 12 indicates the anti-skidding members, and each of which consists of a length of rope, formed from closely woven vegetable fiber. Overlapping each end of a member 12, is the sleeve 6 of a coupling member.- The serrations 7 of the slit ends of the sleeves 6 are pressed against the member 12 for the purpose of connecting coupling members to the ends of the anti-skidding member.

Referring to Fig. 3 the anti-skidding member is indicated at 13 and is formed of a length of rope, of vegetable fiber, and which is not as closely woven as the rope from which the anti-skidding member 12 illustrated in Fig. 1 is formed. The antiskidding member 13 is of greater diameter than the anti-skidding member 12 and the ends of the anti-skidding member 13 have the coupling members 5 secured therewith in the same manner as said coupling members are secured to the ends of the antiskidding members 12.

Referring to Figs. 2, 4, 8 and 9 of the strip of closely woven fabric, of a thickness of about one-fourth of an inch. The coupling member consists of a body portion 16, having a pair of extensions 17 which are bent to overlap the body portion 16, as indicated at 18. Projecting from the body portion 16 is an arm 19, having a hook-shaped free end 20, which is slitted as at 22, and the material freed by the slit is pressed inwardly to provide a securing barb 23, which engages in the retaining member 4. The edges of the body portion 16 and extensions 17 are serrated as at 24, to form teeth, which engage in the anti-skidding member 1& for the purpose of securing the coupling members to the anti-skidding member when the extensions 17 are bent over adjacent the body 16.

Referring to Figs. 6 and 7, which illustrate a modified form of coupling member, the said member consists of a-body portion 25, having serrated edges 26. The body portion is bent to provide a split sleeve 27 which is adapted to surround the end of an anti-skidding member of the type indicated at 12, 13. Projecting from the body portion 25 is an arm 28, having a hookshaped free end 29. The arm 28 is channelshaped as at 30 and extending into the end 2S) is a free end of a resilient retaining member 31, the latter being secured as at 32, to the body portion 25. The arm 28 and memmisses ber 31 provide What may be termed a snap hook and engages with the retaining member 4.

The barbs 11 and 23 extend into the retaining member 4 for the purpose of main taining the anti-skidding members in spaced relation, these latter when in position extend transversely with respect to the tread of the tire.

'VVhat I claim is An anti-skidding device comprising a plurality of anti-skidding members composed of narrow fiat strips of closely woven fabric adapted to extend transversely in flat engagement with the tread portion of a tire, a pair of coupling elements for each of said members, each of said elements comprising a rectangular body-portion and parallel extensions contactingly inclosing one end portion of its associated anti-skidding member, the said extensions and bodyportion being provided with serrated edges pressed into the said end portions whereby the latter is connected to the element, and annular retaining members seated in the said coupling elements.

In testimony whereof I aflix my signature in the presence of two witnesses.
